Definitions
- low loss dielectric materials for instance, solid blocks of polystyrene, polyethylene, or the like, in use are relatively heavy in weight.
- the dielectric materials, such as dielectric antennas being heavy is considered an undesirable feature.
- the plurality of particles may be adhered together using a rubber adhesive or an adhesive comprising of a material in a group consisting of: polyurethane; and epoxy.
- the average end-to-end measurement of each particle of the plurality of particles may be in the range of 0.5 to 5 mm.
- the conductive fibre may have a length in the range of 0.5 to 5 mm and a diameter in the range of 0.005 mm to 1 mm.
- the array may comprise 1 to 10 rows.
- the array may comprise 1 to 10 columns.
- the particles in the example embodiments of the present invention are made using a low-density and lightweight material.
- foam polymers made of polyethylene, with a typical density around 0.01 to 0.02g/cm 3 . It is appreciated that other foam polymers made of materials, such as polystyrene, polytetrafluoroethylene (PTEF), polypropylene, polyurethane silicon, or the like, may be used to make the particles.
